Euphonix Modular I/O Configuration Guide
Product Description
10
Each audio backplane contains 32 passive stereo audio busses (64
total signal paths). Audio source and destination modules are
connected to audio busses via physical on-board jumpers or via
web-browser interface. Any audio buss may have multiple
destinations but only a single source. Different frames have
options to isolate audio busses in certain physical slot positions.
This enables higher signal densities.
•
Control Buss
Each frame contains a single control buss. The control bus
interfaces to LAN via the FC972 Remote module. This enables
console control of mic preamps and web-browser configuration of
certain modules (other modules do not require any external control
and do not appear on the control bus). The FC972 may be
mounted in any frame slot and is assigned a unique IP address.
Up to 16 “controllable” modules may be fitted into a given frame
and each is assigned a unique ID via on-board switches.
•
Sync Buss
Each frame contains a single sync buss that is shared by all
modules in the frame. Several modules may act as the frame sync
source such as the SY983 Sync (single and redundant
configurations available) any MADI module (lock to incoming MADI).
The sync source module(s) must be placed in any of the four red
“reserved” slots located in the rear-plane (slot positions 1-4).
These slots may also be used for other modules. If a MADI module
is used a sync source, the frame must not contain any SY983/982
modules for proper operation.
1.1.1 IO93 Modular I/O Frame
General Description
The IO93 is a 3RU double-sided frame with removable dual-
redundant PSUs capable of delivering 5v@12A of usable
power. The frame contains 19 rear-plane slots and 18 front-
plane slots for modules. Rear-plane slots 1-4 are “reserved”
for the sync source module(s). Other modules may be fitted
here also. Sync and control busses are shared by all slots in
the frame. Audio busses may be isolated between the front
and rear planes via an interconnect PCB located in the unit
